Desperate to find a way out of his situation, Henry begins to see a woman with strange powers who lives in the radiator behind his apartment. She performs a musical number, singing about a world beyond Henry's current reality, and offers him comfort and solace.
As the film progresses, Henry becomes more and more unhinged, leading to a shocking and disturbing finale that is open to interpretation.
